About this test

Sex Hormone Binding Globulin (SHBG) is a protein, made mainly in the liver, that binds testosterone and oestrogen and controls how much of each is free to act in the body. Checking it can help explain low libido or erectile dysfunction in men, and in women can help account for symptoms such as irregular periods, acne or excess body hair linked to elevated free testosterone.

This clinic-based version sits at the median price for the SHBG tests we track. Better2Know's own home kit covers the same single marker for £20 more, while Blue Horizon Medicals offers it for £45.25, a fraction of the price. The difference between the three comes down to where the blood is taken rather than what is tested.

The scores reflect a clearly described, easy-to-book test that loses marks mainly on how results are handled. They are not doctor-reviewed as standard, and collection still needs a clinic or nurse visit rather than a fully at-home kit. Trust reflects Better2Know's Trustpilot rating of 4.2 from 775 reviews, CQC registration and 18 years trading.

Who is it for?

This suits someone happy to attend a clinic or arrange a nurse visit to check SHBG, for instance when investigating low libido, erectile dysfunction, irregular periods or unexplained hair growth. If you would rather avoid a clinic visit, Better2Know's own home finger-prick kit covers the same marker for £195. If price matters most, Blue Horizon Medicals offers the same single test for £45.25.

How it works

A trained professional takes a venous blood sample at a Better2Know clinic or during a home nurse visit (a home finger-prick kit is also available for £195). The sample is sent to the laboratory for analysis, with results reported within one working day of arrival. Results are not doctor-reviewed as standard, though a private consultation can be arranged to discuss them.
